A Chinese space mining company has designed a robot that can capture （捕获） waste material left behind by spacecraft in outer space with a big net.

The state-run Xinhua News Agency recently reported that the robot launched on the government’s Long March 6 rocket along with several satellites. The robot will also explore deep space to observe small objects in the universe. The 30-kilogram robot， called NEO-01， was developed by Origin Space. The company says the robot will lead the way for future technologies capable of mining on asteroids （小行星）.

The world’s first asteroid mining company， Planetary Resources， was established in 2009. Since then， more than 12 businesses around the world have entered the industry， including 3D Systems of the United States and Japan’s Astroscale. Astroscale’s technology uses magnets （磁铁） to gather up space waste. But a report on the Origin Space website says NEO-01 will use a net to capture waste and then burn it. Thousands of satellites have been launched worldwide. As they are used too long， many end up as waste and put other operating satellites at risk.

Su Meng is the founder of Origin Space. He said the company plans to launch many space telescopes and more spacecrafts to begin the first for-profit mining of asteroids by 2045. Su added that NEO-01 will serve as a prototype （雛形） of future space mining robots， which can use rich mineral resources on asteroids to support the development of the space industry.

The Xinhua News Agency reported that China was increasing efforts to land a spacecraft on a near-Earth asteroid to collect materials. China is also speeding up a plan to build a defense system against near-Earth asteroids.

1. Which of the following can correctly describe NEO-01？

A. It weighs 60 kilograms.

B. It is mainly used to catch space waste.

C. It was created by Planetary Resources.

D. It will be burnt after finishing its mission.

2. What can be inferred from Paragraph 3？

A. Magnets were used to burn space waste.

B. Origin Space will open more mines on asteroids.

C. It is the useless satellites that make space waste.

D. The robot will look into deep space for more waste.

3. What does Su Meng think of NEO-01？

A. It’s promising and rewarding. B. It’s a long way to produce it.

C. It has benefited the space industry. D. It will help make money for the company.

4. What can be the best title for the text？

A. NEO-01， A Smart Robot Used in Space

B. A Chinese Robot Can Catch Space Waste

C. A New Robot Makes China a Space Power

D. NEO-01， the Pioneer of Future Space Robots

Livestock （牲畜） cloning is the practice of cloning sheep， cattle and other livestock species as a way to improve efficiency. The basic idea behind livestock cloning is to clone animals that have certain qualities， such as cows that produce more milk or meat. 1

However， this practice is very controversial， and livestock farmers have been hesitant to adopt it fully because of public opposition and certain inefficiencies.

In technical terms， livestock are cloned by taking cells from one animal and using them to fertilize （使受精） eggs. Scientists take the fertilized eggs and put them in female animals. 2 Many animals are born with abnormal shapes. Scientists are looking for ways to improve the process and make it less expensive to adopt on a wider scale.

3 For example， if farmers were able to take only their very best animals and recreate them many times， they could potentially be more productive.

There are also some potential problems with cloned livestock. 4 For example， when a disease hits， there are usually individuals that cannot be harmed by the disease or are more resistant， and they will generally survive. If all the animals were genetically similar， this sort of disease could totally destroy an entire generation of livestock.

In addition to concerns about genetic diversity， there are other concerns about cloning. 5 There are also some people who worry that livestock cloning research may be a gateway to introducing human cloning， which is widely disapproved of.

A. Are the surviving clones really clones？

B. Therefore， the new species are expected to be better.

C. The biggest one arises from a loss in genetic diversity.

D. Cloned livestock have the potential to provide some major benefits.

E. Cloning animals show us what might happen if we try to clone humans.

F. These concerns sometimes come from worries over unforeseen consequences.

G. This process doesn’t always work perfectly， and it can be relatively expensive.

1. _______  2. ______ 3. ______  4. ______  5. ______

Over 48，000 orange trees spread all corners of Seville， Spain. They not only fill the city’s air with the 1 smell of orange flowers in spring， but also 2 over 16，500 tons of fruit every winter. Though that gives Seville the 3 of being Europe’s top orange-producing city， the fruit is too 4 to be consumed fresh. While some oranges are used to 5 jam and alcohol， most of them end up in landfills （垃圾填埋场）. Oranges are a 6 for the city. However， that may change soon thanks to an idea of using the oranges to produce clean energy 7 .

The program is 8 by the city’s council and parks department. Juice got from 9 will be left to ferment （发酵） in an existing biogas equipment. The gas released from the fermented liquid will be used to 10 a machine to produce clean energy. The officials think it’s not just about

Rome—Doctors and medical groups around the world last weekend reacted with strong opposition to the news that an Italian specialist is on the brink of cloning the first human baby.

Dr Severino Antinori， who is the head of a hospital in Rome， has been referred to in an Arab newspaper as claiming that one of his patients is eight weeks pregnant with a cloned baby.

Antinori refused to comment on the reports， but he said he hoped to produce a cloned embryo （卵） for implantation （植入） within two years. So far seven different kinds of mammals have already successfully cloned， including sheep， cats and most recently rabbits.

Doctors showed their doubt and were strongly opposed although they admitted that human cloning would finally come true unless there was a worldwide ban on the practice.

Professor Rudolf Jaeniscb of the Whitehead Institute for Biomedical Research at the Massachusetts Institute of Technology said， “I find it astonishing that people do this where the result can be predicted that it will not be a normal baby. It is using humans as Guinea pigs. It makes people feel sick.”

But Ronald Green， director of the Ethics Institute at Dartmouth College in the US， said it was unlikely that an eight-week-old pregnancy would lead to a birth.

So far all cloned animals have suffered from some different serious disorders， many of them dying soon after their births.

Doctors are opposed to human cloning because they are worried about the welfare （福祉） of the cloned child if there is one.

“There are no benefits of cloned human beings， just harm，” said Dr Michael Wilks of the UK.

1. What does the underlined phrase “on the brink of” in Paragraph 1 most probably mean？

A. On the side of. B. On the point of. C. In search of. D. In favor of.

2. What is the doctors’ general attitude to the cloning of humans？

A. They support it. B. They welcome it.

C. They are against it. D. They pay no attention to it.

3. What can we learn about the cloned animals？

A. They are active.

B. They are born unhealthy.

C. They live a relatively long life.

D. They have a different charactor from the normal.

4. What does the text mainly tell us about human cloning？

A. Its failure. B. Its success. C. The anger at it. D. Voices against it.

Have you ever wished you could see in the dark as well as an animal？ In action movies， we often see characters wearing special glasses that reveal things that can’t be seen in darkness. Everything looks green， but we can see the shapes and outlines clearly. As a matter of fact， this is somewhat similar to the way animals’ night vision （視力） works.

You may have noticed eyeshine in pictures of animals， or seen it for yourself when light hits an animal’s eyes. Dogs， cats， and many other animals have tissue called the tapetum lucidum （光神经纤维层） in each eye. The purpose of this tissue is to reflect light deeper into the eye. For many animals， it leads to their excellent night vision， and it helps them hunt.

Different types of animals have different colors of eyeshine. The light reflecting back from the eyes of dogs and cats is likely to be yellow. Rats and birds usually have eyes that shine red. Other animals’ eyes may reflect white， yellow， green， or pink light. In each case， the color is related to the type of cells that make up the tapetum lucidum， as well as the chemicals inside the cells.

Eyeshine has the function of improving animals’ night vision， but humans have found other uses for it. For example， when people are searching for certain types of animals， their eyeshine may be helpful in recognizing or discovering them. Also， eyeshine has inspired humans to invent substance that reflects light at night. Strips containing this substance are used to warn us of safety risks such as raised parts of roads. Even though humans cannot see so well at night， we have still found ways to benefit from this amazing animal feature.

5. How does the tapetum lucidum help animals’ night vision？

A. It sends out light in the dark. B. It makes everything appear green.

C. It reflects light back into the eyes. D. It enables their eyes to change colors.

6. How does the author develop Paragraph 3？

A. By providing reasons. B. By giving examples.

C. By following space order. D. By doing scientific tests.

7. What can we learn about scientists’ research on eyeshine？

A. They’ve put it to practical uses. B. They’re using it to protect animals.

C. They’re trying to include more animal types. D. They’ve invented special glasses based on it.

8. What is the text mainly about？

A. How animals’ night vision helps them hunt. B. Different colors of animals’ eyes.

C. How animals see in the dark. D. Eyeshine and its benefits.

It seems like technology is everywhere. Computers and smart phones are at the center of almost everything we do. They constantly （持续地） require our attention. We text our friends with them during the day， sleep with them by our beds and check our messages as soon as we wake up.

In the future， technology will no longer be interrupting us all the time. Instead， we will use calm technology which was first developed by scientist Mark Weiser in the 1970s. In his opinion， calm technology works quietly but constantly. We know it is there， but we don’t pay much attention to it. According to Mark， the best technology should be invisible and let you live your life.

We already use many different types of calm technology in our everyday lives. Do you have a smoke alarm in your house？ That smoke alarm is always there， checking the air for smoke and quietly keeping you safe. It only reminds you it’s there when you’ve burnt your bread！ Or there may be lights in your home or school. When somebody passes in front of their sensors， the lights turn on. You don’t think about this type of technology until you see the light go on.

In the future， we can imagine our houses will use calm technology to open the curtains for us in the morning， to turn down the heat when we leave， or even to choose the best music for our mood. The minute we walk through the door， our house will respond by turning on the lights and music， and perhaps even starting to prepare our dinner！

1. According to Mark， calm technology should be .

A. fast and quiet B. fast and smart C. smart but quiet D. quiet but constant

2. Which of the following is an example of calm technology？

A. A computer. B. A smart phone. C. A radio. D. A smoke alarm.

3. What does Paragraph 3 mainly tell us about calm technology？

A. It keeps us safe in many ways. B. It can help you do housework.

C. It has been used in our daily lives. D. It plays an important part in schools.

4. What can we infer about calm technology from the text？

A. It can cure some mental disease. B. It will depend more on smart phones.

C. It will make our life more convenient. D. It can free people from dangerous work.

I was going home by bike in a cold afternoon when my bike broke down. As I was wondering how to do， an old man came over. He offered to help me and soon my bike repaired. I thanked him but asked how to repay him. She shook his head and then told me a story about how a boy had helped him two year before. His story moved me deep. I looked at the man， with my eyes filling with tears. I never thought he could keep such a little thing in the mind for years. Only then do I begin to believe that one good turn deserves another.

背景大调查

Cloning is the asexual production of an exact copy of an original. So for example， one could use cloning to produce the exact copy of a single cell. The cell copy would be identical to the first cell and would have the same exact DNA sequence. In many cases， cloning has been used to reproduce type specific cells. In some instances， cloning of an individual organism， like the sheep， Dolly， has been possible.

Unlike reproduction that involves two “parents”， such as a male and female plants， cloning has a single parent. This is often used in reproducing certain plants. Certain plants have undergone cloning processes for thousands of years， but they do not play a part in the ethical debates that surround cloning of animals， and most particularly humans.

For example， reproductive cloning of animals was first attempted in the 1950s. The sheep Dolly was cloned in 1996. Dolly’s parent had DNA transferred into an egg that had its nucleus removed. This is called a somatic cell nuclear transfer. The cell was then treated with chemicals and stimulated to grow so than an almost exact replicate of the cloned sheep was born.

克隆就是通过无性繁殖，对原体的精确复制。举例来说，细胞就可以被完全复制。生成的细胞与原细胞一模一样，甚至基因链也相同。普通实验都是克隆特型细胞。当然，克隆羊多莉的成功表明有机体的克隆也是可行的。

有些植物分雌雄，其后代有父有母，而克隆产物不同于此，只有一个父源。有很多植物也是单性繁殖，数千年如此而不会有伦理问题；可一旦涉及动物，特别是人类的克隆，伦理问题便凸显了。

有例可证，动物克隆的尝试始于20世纪50年代，多莉于1996年被克隆。将其父源基因移植到一去核卵子中，这一技术被称为体细胞核移植。该细胞随之采用多种化学物质进行培育，最终得到了对其父源完全克隆的多莉。
